1) Hatari must allow to initialize the GEMDOS emulation a second
For the same reason, Hatari GEMDOS drive emulation does not work
after a software reset (Ctrl+Alt+Del).
That's also true for the original TOS (at least for those versions that
support that keyboard combination, like TOS 2.06).
I've committed a fix now (slightly based on your original patch).
Thanks for your detailed report!
While EmuTOS works with this version, and TOS >= v2,
all the older TOS versions get now double bus error
right at start if GEMDOS HD or tracing is enabled:
Bus error wput at 0041fffe
Bus Error at address $41fffe, PC=$fc0170 addr_e3=fc0174 op_e3=3302
Illegal instruction: 000a at 08FA02E2 -> 04FC0B0A
I.e. for some reason PC value returned by WinUAE M68000_GetPC()
has garbage data on the highest byte, and therefore your check
for cartridge area address doesn't match.
